抜粋

A comparative study on the performance of 256-QAM and improved-efficiency 225-QPRS in distorted channels is presented. The computer-simulated results shows that with the same spectral efficiency of 6. 3 b/s/Hz, 256-QAM is less sensitive to parabolic and sinusoidal group delay distortions and linear amplitude distortion, whereas 225-QPRS is less sensitive to linear group delay distortion and parabolic and sinusoidal amplitude distortions.
